<P>PROBLEM TO BE SOLVED: To provide a liquid crystal display of a vertical alignment mode having excellent uniformity using a retardation plate which might generate the problem of unevenness by conventional usage, to provide a set of a composite polarizing plate which can be used for the same and to provide its manufacturing method. <P>SOLUTION: A pair of polarizing plates 10 and 40 are disposed on both surfaces of a liquid crystal cell 50 vertically aligned in a no voltage applied state and a pair of retardation plates 20 and 30 are disposed between the liquid crystal layer 50 and the respective polarizing plates to form the liquid crystal display. The pair of retardation plates 20 and 30 have a relation of nx>ny≥nz, when refractive indices of two axis directions in the film surfaces thereof are defined as nx and ny and when refractive index in the thickness direction is defined as nz, and delay phase axes 25 and 35 of the two retardation plates cross at 88.5 to 91.5° angle. When the polarizing plates and the retardation plates are stuck to manufacture composite polarizing plates for front and rear surfaces, the upper and lower sets of composite polarizing plates can be manufactured by reversing the front and the rear surfaces of the retardation plates to stick the retardation plates to the polarizing plates. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
